we can't startup Java instance after DRP action, on SAP BW

[Former Member]

we have tried to restore a sap-oracle database with synchronisation via

Mirroview, the target systems are BW and Java instance.

but we have detected problems when we wanted to install java lisence andconfigure BEX module.

message errors are as follows :

com.sap.engine.bootstrap.SynchronizationException: Database

initialization failed! Check database properties!

com.sap.engine.frame.core.configuration.ConfigurationException: Error

while connecting to DB.

Caused by: java.sql.SQLException: Io exception: Broken pipe

[Jun 18, 2009 11:48:49...] [Bootstrap module]> Problem occurred while

performing synchronization.

I 'd like to add some points. At Oracle level all is fine. The context

is a DRP exercise with the luns cloning by the disk array. The systems

cloned are a source system (ABAP stack), a BW (ABAP STACK) and a J2EE

system (JAVA stack). Only the BPJ has a problem to startup. After a

while, jlaunch andjcontrol processes die. Application is unusable. In

the logs, the remaining messages are issue about DB connection,

synchronisation issue with the bootstrap....

The Way Java syystem work is there is a synchronization between Java DB and filesystem

So in the event you have restored your Database you need to restore SAP filesystem of that time stamp

Below is the procedure of Restoring a java System

1. Install a new SAP Web AS Java system using SAPInst (If you dont have a filesystem backup ) or restore the file system from the offline backups that you created.

2. Import the database backup using the relevant tools provided by the database vendor.

3. Overwrite the SAP system directory /usr/sap/<SID>.

4. Restart the system

Hope it helps

Cheers !
